Multiple choice

Which of the following is not a common method of soil remediation?

  1. Phytoremediation

  2. Bioremediation

  3. Landfilling

  4. Incineration
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Multiple choice

Which of the following is NOT a common form of environmental injustice related to waste management?

  1. Siting waste facilities in low-income communities

  2. Denying access to waste collection and disposal services to certain communities

  3. Charging higher fees for waste collection and disposal services in certain communities

  4. Providing better waste management services to certain communities than others
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Siting waste facilities in low-income communities, denying access to waste collection and disposal services to certain communities, and charging higher fees for waste collection and disposal services in certain communities are all common forms of environmental injustice related to waste management. Providing better waste management services to certain communities than others is not a form of environmental injustice.

Multiple choice

Which of the following is NOT a common method of waste reduction?

  1. Recycling

  2. Composting

  3. Landfilling

  4. Incineration
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Recycling, composting, and incineration are all common methods of waste reduction. Landfilling is not a method of waste reduction because it does not reduce the amount of waste generated.

  2. Reduces the amount of waste sent to landfills

  3. Creates a nutrient-rich soil amendment

  4. Increases waste disposal costs
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Produces biogas, which can be used as a renewable energy source, reduces the amount of waste sent to landfills, and creates a nutrient-rich soil amendment are all benefits of anaerobic digestion. Increases waste disposal costs are not a benefit of anaerobic digestion.

Multiple choice

Which of the following is NOT a benefit of incineration?

  1. Reduces the amount of waste sent to landfills

  2. Produces energy

  3. Creates a nutrient-rich soil amendment

  4. Reduces greenhouse gas emissions
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Reduces the amount of waste sent to landfills, produces energy, and reduces greenhouse gas emissions are all benefits of incineration. Creates a nutrient-rich soil amendment is not a benefit of incineration.
